STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT

BACKGROUND Field of the Disclosure

This disclosure generally relates to a heat exchanger unit with characteristics of improved: airflow, noise reduction, cooling efficiency, and/or structural integrity. Other aspects relate to a system for monitoring airflow through a heat exchanger unit, or fouling related thereto. In particular embodiments, a monitoring module is mounted externally to the heat exchanger unit of a monitored system, the system being usable to monitor fouling of the unit, and provide an associated warning. The heat exchanger unit may be used for cooling various utility fluids used with a heat generating device, such as an engine, a pump, or a genset. Other embodiments pertain to a method of monitoring fouling, as well as a method for using a monitoring system.

Background of the Disclosure

Whether its refrigeration, hot showers, air conditioning, and so on, the function of heating and cooling is prevalent in today's residential and industrial settings. One area of relevance is the oil and gas industry, including exploration, upstream, and downstream operations where the ability to heat and/or cool is critical. Upstream operations can include drilling, completion, and production, whereas downstream operations can include refining and other related hydrocarbon processing, all of which utilize a vast amount of process equipment including that which provide heat transfer. To be sure, the background of the disclosure is relevant elsewhere, but for brevity discussion is focused on O&G.

Common settings are nothing short of challenging in the sense that in many instances operations and processes (and related equipment) are exposed to environmental conditions, such as extreme heat, cold, wind, and dust (including natural amounts of particulate, as well as that caused by the operation of equipment and vehicles).

It is routine to have (indeed, need) some type of heat exchange ability in such settings. As set forth in U.S. Ser. No. 15/477,097, an example operation in an industrial setting may include one or more frac pump units. Each unit is typically operable with a pump and engine mounted or otherwise disposed thereon, as well as a radiator (or analogously referred to as cooler, heat exchanger, etc.). As mentioned before, equipment like this must be rugged and durable in order to have long-term operational capacity and effectiveness.

The radiator is configured for cooling one or more hot service fluids associated with the equipment of the frac pump unit, such as lube oil or jacket water. The radiator typically includes a ‘core’ of stacked fins, with one part of the core providing a flow are for the service fluid(s), while another part of the core is provides a proximate, albeit separate, flow area for ambient air. A fan is used to blow or pull air through the stacked fins, the air being a low or moderate enough temperature to cool the service fluid, which is then recirculated in a loop.

The stacked fins often have a configuration that is tantamount to an extensive amount of small air passageways proximate to (albeit separate from) service fluid passageways, whereby the air and the service fluid can ‘exchange heat’ via the surface material of the stacked fins between the passageways (e.g., aluminum).

Over time airborne dirt in and other particulate in the air will begin to deposit on the air intake side (and elsewhere), resulting in a fouled radiator. Fouling can seriously deteriorate the capacity of the surface of the fins to transfer heat under the conditions for which they were designed. Among other problems, the fouling layer has a low thermal conductivity which increases the resistance to heat transfer and reduces the effectiveness of heat exchangers. In addition, fouling reduces the cross-sectional area in the passageways, which causes an increase in pressure drop across a heat exchanger.

Radiator fouling affects both capital and operating costs of heat exchangers (and overall processes). Higher capital expenditures include that for excess surface area (for heat transfer), extra space, and transport and installation costs. Operating expenditures include that for energy losses due to the decrease in thermal efficiency, increases in the pressure drop through process equipment, and production losses during planned and unplanned plant shutdowns for fouling cleaning.

Moreover, government emissions regulations are forcing engine manufacturers and their customers to reduce emissions from reciprocating engines. Current solutions involve returning the exhaust through heat exchange, which elevates combustion temperature and puts significantly more heat into the cooling system. Tier 4 Final (US and CA) Emission regulations come into effect in 2017 & 2020 will force end users into significant equipment redesign industry wide. See, e.g., http://www.assocpower.com/eqdata/tech/US-EPA-Tier-Chart_2004-2017.php, for general reference.

In summary, fouling of heat transfer surfaces is one of the most important problems in heat transfer equipment. Some have described fouling as the major unresolved problem in heat transfer. Equipment operators world-wide are also trying to reduce maintenance costs. One of the highest maintenance costs any piece of equipment has is cooling system maintenance.

And yet despite these detriments, consideration of improved remediation or management techniques have been largely ignored and unchanged. Conventional techniques include mitigation (such as upstream filtering) and chemical treatment.

Mechanical cleaning is also used, but only during predetermined periodic intervals, namely during a planned shutdown or when an exchanger reaches a point of failure and is no longer operable. This approach relies on extensive cost and resource being allocated toward the antiquated philosophy of operational redundancy.

There is a need in the art to overcome deficiencies and defects identified herein. There is a need in the art to reliably monitor fouling of a radiator. There is a need in the art to provide a real-time warning indication about fouling conditions of a radiator.

There is a need in the art for a monitoring system that is durable for use in outdoor and other difficult environmental conditions. There is a need in the art for a monitoring system capable of high degree of sensing accuracy, yet impervious to or otherwise able to withstand external conditions.

There is a need in the art for a method of doing business that includes monitoring and servicing of radiators, especially when the radiator reaches various stages of fouling or provides other indication requiring attention. There is a need in the art to clean a fouled radiator with little or no downtime.

There is a need in the art for a monitoring module that can be retrofitted to any existing heat exchanger, including of great importance to a heat exchanger that has one or more sides (or surfaces) exposed to ambient air.

There is a particular need in the art for a monitoring system that is readily adaptable and compatible to radiators associated with different pieces of heat generating equipment, such as an engine, a motor, a pump, or a genset useable in a wide range of settings.

Referring now to FIGS. 1A and 1B together, an isometric view of a monitored heat exchanger system that includes a monitoring module, a heat exchanger unit, and a heat generation device operably coupled together, and an isometric component breakout of a monitoring module associated with a heat exchanger unit, respectively, in accordance with embodiments disclosed herein, are shown. Embodiments herein apply to a heat exchanger unit that may be an inclusive assembly of a number of components, subcomponents, which may be further associated with operable systems, subsystems, assemblies, modules, and so forth that may overall be referred to as a system, such as heat exchanger monitoring system 201 (or monitored heat exchanger system).

The heat exchanger unit (or HX unit) 200 may include a solid integral frame (or skeletal frame) or may be a frame 202 that includes a number of elements arranged and coupled together. The simplified diagram of FIG. 2B illustrates the HX unit 200 coupled with a heat generation device 203. As can be seen a hot service fluid F_(hot) may circulate from the HGD 203 to the HX unit, be cooled via core 206 (also sometimes recognizes as a cooler or radiator, or part thereof), and recirculate as a cooled service fluid F_(cool) back to the HGD 203. Other equipment including other piping, valves, nozzles, pumps, tanks, etc. need not be shown, as one of skill in the art would have an understanding of coupling the HX unit 200 with the HGD 203 for operable transfer of one or more service fluids therefrom.

As shown system 201 may include the use of a monitoring module 1000. The monitoring module 1000 may be usable for monitoring one or more conditions, properties, characteristics, etc. associated with the operation of the HX unit 200. As an example, the monitoring module 1000 may be configured and used for measuring fouling associated with the core 206.

The module 1000 may be a modular assembly having various components and subcomponents associated and operable together, and like that described herein. The module 1000 may be sized and optimized accordingly for operable coupling with any type of radiator, including that associated with the HX unit 200. One of skill in the art would appreciate the monitoring module 1000 could be retrofitted to equipment already used in the field. Just the same the monitoring module 1000 could come associated and operably engaged with newly fabricated equipment. In aspects, a single HX unit 200 may have multiple monitoring modules 1000 associated therewith.

The module 1000 may be coupled to the frame 202 on a respective side of the HX unit 200 (including in place of a rock grate [not shown]). As shown, the module 1000 may include a mounting frame 1001. The mounting frame 1001 may be an integral piece having a first mounting frame side 1002, a second mounting frame side 1003, a mounting frame top 1004, and a mounting frame bottom (not shown here). The mounting frame may have a cover panel or guard 1007, which may be integral or coupled therewith. Analogous to the mounting frame 1001, the cover panel 1007 may have a first cover panel side 1008, a second cover panel side 1009, a cover panel top 1010 a, and a cover panel bottom 1010 b. Although quadrilateral in the general sense, it is within the scope of the disclosure that the mounting frame 1001 and/or the cover panel 1007 may have different shapes, including as might be necessary to be mounted with a different shape HX unit or radiator core.

As shown in FIG. 1A, the cover panel 1007 may have a plurality of cover panel apertures 1012 configured to coincide with a respective plurality of mounting frame apertures 1014 a. Likewise the mounting frame 1001 may have a plurality of other mounting frame apertures 1014 b configured to coincide with a respective plurality of apertures 282 of the frame 202.

One of skill would appreciate the mounting frame 1001 may be connected to the frame 202 via insertion of a plurality of connectors (fasteners, etc.) 1013 through apertures 1014 b and 282, which may be screws, nut/bolt, quick disconnect, etc. Similarly, the cover panel may be connected to the mounting frame 1001 via insertion of a plurality of cover connecters 1011 through apertures 1012 and 1014 a. The use of a separable mounting frame 1001 and cover panel 1007 allows for simple connect and disconnect from each other, which may make it easier for tasks such as maintenance or cleaning. In this respect the panel 1007 may be easily attachable and removable from the HX unit 200.

There may be a dampener(s) 1018 disposed between various components. For example, there may be one or more dampeners 1018 disposed between the frame 202 and the mounting frame 1001. Analogously, there may be one or more dampeners 1018 disposed between the cover panel 1007 and the mounting frame 1001. The dampener(s) 1018 may be suitable for reducing vibration stemming from operation of the heat exchanger unit 200 that may otherwise be induced into or received by the monitoring module 1000. The dampener 1018 may be one or more layers of a rubbery material, which may have one or more sides with an adhesive thereon.

The cover panel 1007 may have a front side 1019 and a back side 1020. From a reference standpoint the front side 1019 may be that which tends to face outward or away from the HX unit 200. Or where the cover panel 1007 may be considered exposed or external to the surrounding environment. The back side 1020 of the cover panel 1007 may be associated with one or more sensors 1021. The monitoring module 1000 may have a number of different types of sensors associated therewith, including pressure, temperature, noise, etc. Sensor 1021 may be referred to as an airflow sensor, in that the operation of sensor 1021 may help measure, determine, or otherwise sense airflow 216 moving into (or out of) the HX unit 200. In aspects, there may be about 1 to about 25 sensors 1021 associated with module 1000. However, the number of sensors 1021 is not meant to be limited, and may change depending on desired monitoring requirements for a given type of heat exchanger.

The sensor 1021 may be mounted to the cover panel 1007, and operated in a manner to sense airflow into the HX unit 200 as a result of suction. However, the sensor 1021 may just as well be mounted and operated in a manner to sense airflow out of the HX unit 200 (as a result of blowing). The sensor 2021 may be operated and setup to detect airflow through the core 206 during a clean, unfouled state, which may then be used as a baseline. As the HX unit 200 fouls, airflow through the core 206 may be effected, and the electrical signal generated by the sensor 1021 will have a measurable, detectable change in signal strength.

In some embodiments, the configuration (including its size, type placement, etc.) and operation of the sensor 1021 is believed of significance. For example, the sensor 1021 may need to be robust and durable, yet not of any (or as minimal as possible) effect on the operation of the HX unit 200. For example, a sensor that has an orifice may be just as prone to fouling and plugging, and ultimately failure and inability to measure airflow. Other sensors that are large or bulky may be cost prohibitive and/or attribute to unacceptable pressure drop attributable to the monitoring module.

As shown the sensor 1021 may have a rotating member 1024 (rotatable around an axis) with a plurality of blade members 1023 extending radially therefrom. The blade members 1023 may be configured to induce movement of the rotating member 1024 (rotatable about an axis) much in the same way the blades of a windmill function. That is, upon movement of air thereby, at least a minor amount of force (the amount of force being dependent upon the amount of movement of air) will be felt by the blade members 1023, and as a result of being connected to the rotating member 1024, induce rotation of the member 1024.

The rotating member 1024 may be associated with one or more bearings, whereby the rotating member 1024 may be freely movable with respect to a sensor housing or chassis 1025. In aspects, the rotating member 1022 may have a shaft or rotor, and the housing 1025 may be configurable as a (pseudo) stator. The sensor 1021 may have various circuitry and hardware associated therewith, whereby rotation of the shaft may induce or generate an electric current (e.g., via inductive properties attributable to a rotor/stator configuration).

The sensor 1021 may thus be configured to generate an electric current (or in the analogous sense, a voltage) proportional to an amount of rotation. The current, or really, a signal, may then be communicated to a microcontroller (1006, FIG. 1C), which may be part of a logic circuit of the monitoring module 1000. To be sure, sensor 1021 in other embodiments may be able to communicate other forms of sensed information, such as, for example, rpm related to the rotating member.

Referring briefly to FIG. 1C, a component breakout view of a controller housing usable with a monitoring module, and having various internal components, according to embodiments of the disclosure, is shown. Equipment, such as hardware and software, pertaining to the logic circuit may be operably arranged within a controller housing 1016 (which may have a controller housing top 1016 a).

The controller housing 1016 may be weatherproof and dustproof, and this may have an ability to protect internals from undesired environmental and harsh weather conditions. The housing 1016 may be mountable to housing mount 1015. The housing 1016 and housing mount 1015 may have corresponding openings 1017 a, 1017 b, respectively, for accommodating the passing of wires and other circuitry therethrough. The openings 1017 a,b may be sealed, such as with silicone.

The controller housing 1016 may be configured with suitable components and hardware for that accommodate or provide functionality of the monitoring system 201. Such components may include, for example, the microcontroller 1006 (in operable communication and connected with sensors 1021 via wiring, circuitry, and so forth), a regulator (such as a voltage regulator) (not shown here), a power supply or battery (or battery cell) 1027 a, a charger (e.g., battery charger) (not shown here), solid data storage 1028, a Wi-Fi module 1029, a GSM module 1030, a CAN-Bus module 1031, and various indicators, such as audio or visual (e.g., RGB LEDs) 1032.

Referring now to FIGS. 1A, 1B, and 1C, together, the microcontroller 1006 may be readily useable and compatible with various hardware, including switches, LED's, and sensors. The microcontroller 1006 may include HDMI output to a screen such as a TV or a monitor, as well as wirelessly communicating to smart phones or computers via Wifi or Bluetooth.

A signal from the microcontroller 1006 may generate a signal communicable as a message or other form of warning, including by way of one or more of audio, video/visual (e.g., Green, Yellow, Red LEDs), email, SMS/text, CAN Bus, such as J1939. Thus, the module 1000 may include a LED response interface. In embodiments, LED lights may be configured to provide varied warnings based on monitoring and detection. For example, and with respect to certain percentage of fouling, the LED lights may flash green (0-25% fouled), yellow (25-75% fouled), or red (75-100% fouled). In a similar manner, a warning may be transmitted (e.g., text/SMS, push notification, email, J1939, etc.) based on a percentage of fouling.

Software herein may be able to read values from the SD card and create a look-up table.

Referring now to FIGS. 2A and 2B together, a logic circuit process flow diagram and a logic circuit decision tree operable as part of a monitoring module, respectively, according to the embodiments of the disclosure, are shown.

Generally, in terms of hardware and related architecture, the logic circuit may include one or more microcontrollers 1006, memory or data storage 1028, and one or more I/O devices (not shown), which may all be operatively communicatively coupled together, including such as circuitry, pins, and via a local interface (not shown).

The local interface may have additional elements, such as controllers, buffers (caches), drivers, repeaters, and receivers, to enable communications. Further, the local interface may include address, control, and/or data connections to enable appropriate communications among the aforementioned components.

The I/O device may include devices configurable to communicate both inputs and outputs, such as a router, a telephonic interface, a modulator/demodulator or NIC (that may be suitable to access remote devices, other files, devices, systems, or a network), a radio frequency (RF) or other transceiver, a bridge, and so forth. The I/O devices may include one or more components for communicating over various networks, such as the Internet or intranet.

In aspects, external computers (and respective programming) may be communicably operable with the logic circuit (and thus monitoring module 1000).

In operation of the logic circuit, the microcontroller may: execute software stored within the memory; communicate data to and from the memory; and/or generally control operations of the logic circuit pursuant to the software.

In Operation (with logic)

The operation of the logic circuit may be further understood with an explanation of the tree diagram of FIG. 2B. The tasks are numbered in above the task name. Task 1 is to acquire data from the sensors 1021. This may include sampling the data from the sensors 1021 over a short time (e.g., 60 seconds) and taking an average and standard deviation. Task 2 compares the standard deviation of the new data with a predetermined acceptable limit saved on a memory of the system. This allows sporadic or outlier data to be excluded. This consequently ensures that, for example, windy conditions will not be interpreted as fouling, and thus preventing false alarms.

If the sampled data is sporadic and not acceptable, a delay (task 5) will be implemented to retry (or loop) for data acquisition. Either the data will be acceptable or will remain sporadic. If the sporadic data is very consistent and the number of sporadic data occurrence exceeds a predefined value (task 3), the user is notified of an error (task 4) (typically an installation error).

Once the sampled data of task 1 has been accepted, it is checked with a lookup-table (LUT) flag (task 6), which is essentially a binary that allows for the completion of the fouling lookup-table. This flag indicates if the fouling lookup-table is already generated and exists or not (Initially and during installation, this flag is false, meaning that the table is not yet generated). If the LUT flag from task 6 is false, the programming uses an averaging method to create a fouling lookup-table containing the data output of the sensors 1021 in a clean condition (tasks 7 and 8). After generating the LUT through multiple iterations (averaging), the system turns the LUT flag true.

If the LUT flag is true, the overall fouling is then calculated in task 9. This consists of referencing acquired data from the sensors 1021 against the fouling lookup-table which represents a clean condition. If fouling is evident, a foul state is recorded (task 10). In task 11, the fouled state is evaluated. If consecutive data has determined that the radiator is in a severe (as defined by the user) fouling condition, then the user will be notified using one or more of the defined warning methods (task 10), e.g., LED, email, J1939 message, etc. If the foul count is not too high, a delay will occur (task 12), and the system will continue to collect data to proactively warn the user in case of any fouling.

Referring now to FIG. 3, a side view of a monitored heat exchanger system that includes a monitoring module, a heat exchanger unit, and a heat generation device, operably coupled together, in accordance with embodiments disclosed herein, are shown. Embodiments herein apply to a heat exchanger unit that may be an inclusive assembly of a number of components and subcomponents. The heat exchanger unit 300 may be part of an overall system 401 that may be monitored. Monitored system 301 includes at least one monitoring module 1000, as described herein. While it need not be exactly the same, system 301 may be like that of system 201 of FIGS. 1A-1C, and components thereof may be duplicate or analogous. Thus, only a brief discussion of system 301 is provided, recognizing that differences, if any, would be discernable by one of skill in the art, especially in view of U.S. Ser. No. 15/477,097 being incorporated herein by reference for all purposes. Accordingly it would be further understood that aspects of system 301 may include various additional improvements related to airflow, noise reduction, cooling efficiency, structural integrity, and combinations thereof.

The HX unit 300 may include one or more cores 306 being associated with respective monitoring module(s) 1000. It should be apparent that while HX unit 300 may have a plurality of sides (or side regions), each of the plurality of sides having respective coolers, not every side need have a monitoring module 1000. Still, it may every well be that every cooler is monitored via one or more modules 1000. Moreover, while the module 1000 may be particularly useful for monitoring fouling, other conditions of the HX unit 300 (or system 301) may be monitored.

One or more cores 306 may be associated with and proximate to a respective protective grate (not viewable), which may be useful for protecting fins of the core 306. The monitoring module 1000 may be installed in place of the grate.

Although not shown in entire detail here, the HX unit 300 may include a fan system. Briefly, the fan system may include related subcomponents, such as a fan that may be understood to include a rotating member with a plurality of fan blades extending therefrom. The fan may be operable by way of a suitable driver, such as a fan motor, which may be hydraulic, electrical, gas-powered, etc. Conduits may be configured for the transfer of pressurized hydraulic fluid to and from the motor. As such, pressurized hydraulic fluid may be used to power the motor.

The fan system may include a fan shroud, which may be generally annular. The fan shroud may be coupled to the frame via connection with the top plate. The shroud may include one or more lateral openings 360 to accommodate the passing of the mount bar 309 therethrough. The mount bar 309 may be a rigid bar or beam that extends from one side 359 a of the HX unit 300 to another side 359 b.

A fan rock guard 347 may be coupled to a shroud 313. The shroud 313 may be proximate to an aeroring (not shown). The aeroring may be annular in nature, and have a ring cross-section that may have a radius of curvature. Thus, the aeroring may have a rounded surface that may aid in improving airflow and reducing pressure in and around the fan system. Without the aeroring, eddies and other undesired airflow may occur in corners of the top of the frame.

The configuration of the shroud and aeroring may provide added ability for further streamlining airflow, which may beneficially reduce overall power requirements.

The fan system can be operable to draw in and direct the flow of air 316. The air 316 may be drawn through the sides of the HX unit 300 (and respective cores, which may then be used to cool one or more utility fluids F) and out as heated exhaust 318. The benefit of such a configuration is the ability to provide cooling in parallel, versus series. In a series configuration, the airflow becomes progressively hotter as it passes through each cooling circuit, resulting in a loss in cooling efficiency. This can be especially problematic where ambient air temperature is usually hotter, like Texas and Oklahoma.

Utility fluid F (or multiple F's) may include by way of example, lube oil, jacket water, turbo (such as for an engine), transmission fluid (such as for a pump), and hydraulic fluid (such as for the fan drive).

One of skill in the art would appreciate that airflow through the core 306 may be generally in a path parallel to a horizontal axis. In an analogous manner, the fan 308 may have an axis of rotation generally parallel to a vertical axis. Accordingly, airflow through the HX unit 300 may be transitioned from (approximately) horizontal to vertical as the airflow moves through the core 306 and out the fan exhaust 318.

As such, by way of example, utility fluid Fi may be transferred from a heat generating device 303 at a hot temperature into an HX unit inlet 378, cooled with airflow via core 306, and transferred out of an HX unit outlet 384 back to the HGD 303 at a cooler temperature. While not meant to be limited, HGD 303 may be an engine, a genset, a motor, a pump, or other comparable equipment that operates in a manner whereby a utility fluid is heated.

There may be one or more cores 306. A ‘cooler’ or ‘cooling circuit’ may include one or more cores 306. The HX unit 300 may have between about 1 to about 8 cooling circuits, which each may be configured for cooling in parallel to each other.

The HX unit 300 may include various sound reduction or integrity features like that as described in pending U.S. patent application Ser. No. 15/477,097, such as various sound baffle configurations and/or flexible mount assemblies.

In operation, a utility fluid F from HGD 303 may be transferred into the HX unit 300. The transfer may be direct or indirect (such as from a holding tank). Within the unit 300, the fluid may flow into a tank chamber (not shown) via inlet 378 of inlet tank. The fluid then distributes into the various alternating layers and respective channels of the core 306.

Similarly airflow 316 may be drawn into HX unit 300, and into the various perpendicular and alternating layers and respective channels of the core 306. The HX unit 300 may be configured for passing atmospheric air through or in contact with the core 306, so as to reduce the temperature of the service fluid circulated through the core 306. In this respect, a fan (or fan system) may be rotatable about a fan axis so as to draw in (or suction, etc.) atmospheric air inwardly through channels (or fins 373), resulting in airflow through the core 306.

The service fluid F_(1-hot,) having a temperature hotter than the airflow, may be cooled (and conversely, the airflow warms). Cooled service fluid F_(1-cold) com leaves the cooling circuit via a fluid outlet 384. Various piping, tubing, etc. may be connected to the tank outlet 384, as may be desired for a particular application, and as would be apparent to one of skill in the art. In some aspects, the tank outlet 384 may be in fluid communication with an inlet of a subsequent cooling circuit also connected with the frame 302.

Cooled utility fluid may be returned from the HX unit 300 to a source tank, or directly to the HGD 303. Thus, service fluid from the HGD 303 may be circulated in a cooling circuit in a systematic and continuous manner. As will be appreciated, a suitable circulating pump (not shown) may be provided to circulate the service fluid through the core cooler 306.

Other coolers of the HX unit 300 may be generally similar in nature, and suitably configured for the cooling of various service fluids from the HGD 303.

Embodiments herein provide for a system (and related method of operating or using the system) using on or more components described herein. For example, such a system may include a wellbore and other wellbore and production equipment, as well as a frac trailer. The frac trailer may include a frac pump, a HGD, and a HX unit as pertaining to the disclosure.

Other embodiments herein provide for a method of doing business related to a monitored heat exchanger system. The method may include the steps of having a customer relationship between a provider and recipient (i.e., customer, client, etc.). The method may include charging a one-time or ongoing fee related to the monitored system. The provider may install the monitored heat exchanger system as a new standalone skid. Alternatively, the provider may retrofit existing equipment for operable communication with a monitoring module as described herein. Thus, in embodiments there may be a first transaction related to equipment purchase or use, followed by a second transaction related to installation.

Another part of transaction, or alternatively, a separate transaction, may pertain to a license for the use software (or programming) related to a logic circuit of the monitoring module, as the provider may own copyright in the respective software (or be an exclusive licensee).

The provider may provide services and equipment directly, or may use a subcontractor.

Once a recipient has completed its applicable transaction, and the system has been associated with at least one monitoring module, the recipient may be provided with the capability to track and monitor one or more characteristics or properties respective to an individual heat exchanger unit performance. Reported information (or parameters) may include percentage of fouling, time between warnings, cleaning frequency, etc). This information may be groupable by location or region to see if one is performing better than another. The system may also indicate them how many units are in green, yellow or red, which may further help identify problem regions, operators etc.

The method may further include a field service component. That is, the provider, or affiliated field service business, may be able to offer (give, etc.) a solution, whereby the monitored system sends out an alarm of some variation, such as SMS/text, email, etc. In this respect the recipient has the option to address the alarm, or have the provider tend to. In other words, in the event the monitored system provides a warning about, for example, a dirty radiator, the recipient is prompted to find a remedy that can alleviate or mitigate process downtime.

The business method may thus include steps pertaining to receiving a warning via the monitoring module, and selecting a remediation option, such as cleaning with dry ice or a pressure washer or in their yard when the pump comes back in from the field. In aspects, these steps may be handled remotely and/or off the jobsite. Accordingly, the recipient need not even have to take any action, as the provider may handle all steps.

The business method may include providing an incentivized transaction if the monitoring module is used with a HX unit that is sold by the provider. The monitoring module may have components as described herein, and the HX unit may likewise have components of any HX unit described herein.
